Amsomia Foamy Sponges 2
Amsomia Rockwool 2
Datura Lt. Blue Rockwool 4
Datura Lt. Blue Foamy Sponges 4
Datura Double Yellow Rockwool 1
Datura Double Yellow Foamy Sponges 1
Morning Glory Blue and Pink Silks Rockwool 6
Morning Glory Blue and Pink Silks Foamy Sponges 6
Morning Glory Blue and Pink Silks Cellulose Sponge 5

The daturas, acers, and amsomia have done nothing yet but the results of the morning glories is interesting.

Rockwool 5 out of 6 have germinated
cellulose 3 out of 5 have germinated
foamy 3 out of 6 have germinated
The interesting part is that the ones in rockwool are all ready larger than either of the others.
Next best is the cellulose sponges with the foamy ones coming in last.
I will post a couple photos for you to see, but so far the rockwool is definitely winning hands down.
I really wish I had some of those cocoa cube things to play with too. I just can’t justify buying many more toys.
I probably will keep using the sponges, I am still happy with the results I am having, the cellulose ones do hold moisture better, so I think I will switch to those. I will save the rockwool for the things like brugs that I want to be very successful with.

These are the ones in Cellulose

Here are the foamy sponges, although there isn’t much to see, I had to open a little to see that they did have roots and had started to develop.

Thanks for the report. (It looks like you have been having too much fun.)
I think I’ll be getting some cellulose sponges. Looks like a really good way to start seed to go into a hydroponic system.

Much to my amazement this afternoon when I looked the sponges are trying to catch up. I don’t think the foamy ones will but the cellulose might. It is incredible have fast these have sprouted. I did not nick these seeds at all and they have started much faster than the ones I did nick.
I guess thats a lesson in itself.

Alice: Thanks for starting the experiment! I have a similar one going with brug seeds. Nothing yet 🙁

What was the date that you planted these? I’m curious about the germination time on your MG’s — I planted 20 Heavenly Blues in RW last night. Thanks! Gretchen

I started everything on 1/26 and the picture thats posted is from 1/29 so you can expect some pretty fast results from the morning glories.
I should go take another picture because I am amazed that the sponges are starting to catch up, although I think the rockwool cubes are developing roots faster.
It really is fascinating, I promise some pictures later today and I will try to do some of the roots to.

I just posted this information in your thread. Not sure which thread is the most appropriate one. Here it is again.

What are the different types of hydroponic media?

Rockwool is a fairly recent addition to the types of growing mediums available on the market. This sterile, porous, nondegradable medium is composed primarily of granite or limestone which is melted and spun like cotton candy. Rockwool is then formed into blocks, sheets, cubes, slabs, or flocking. Rockwool absorbs moisture without holding nutrients, and even when it is completely saturated still retains 20% air for your root system.

L.E.C.A. stone is a type of clay which is super-fired to create a porous medium. It is also heavy enough to provide secure support for your plants’ root systems. This non-degradable, sterile growing medium holds moisture, has a neutral pH, and also will wick nutrient solution to the root systems of your plants. L.E.C.A. is often the growing medium of choice of novices and professionals alike because it is easy to use.

Perlite is primarily composed of minerals subjected to intense heat which expand and become very absorbent. This material is light, has a neutral pH, excellent wicking action, and is very porous. Perlite is used in a wide variety of hydroponic systems because of its ability to hold moisture and nutrients as well as air, and also because it is very easy to use.

Coconut Fiber
An alternative to using rockwool, Coconut fiber is the first “organic” medium to offer high performance in modern hydroponic applications. Coconut fiber can also be added into soil mixtures to increase water holding capacity. Coconut fiber holds more oxygen than rockwool and is pH neutral. Available as compressed bricks, when Coconut fiber is soaked in water it expands to 6 times its compressed size. Many growers have found that a 50/50 mix of coconut fiber and L.E.C.A is the perfect organic medium.

Thanks so much for the info, I have been looking in a catalogue that I had gotten recently trying to figure out something that would work as well as the rockwool. I don’t like the feel of the rockwool (it reminds me of insulation) so it is not as user friendly for me as the sponges are. I like the sponges because I don’t have to worry about cutting etc., but so far the results in the rockwool far surpass the sponges for the brugs.

Here are some silk rose morning glories after less then 48 hours in rockwool. No nicking or presoaking.

Here is my Double White Datura after 48 hours. No nicking, no pre-soak.

aknapp, I’ve got my cellulose sponges, did you rinse yours in bleach water same as the foam sponges?

I rinsed my sponges in a 10% bleach/water solution.

Here’s a picture of a Pride of Barbados seedling. I planted the sponge in a 2″ peat pot with a little soil a few days ago. Its doing great!

skyeblu Yes I did them the same way that I did the foamy ones.

Gretchen those look great.

I am really upset with myself. I don’t think my daturas are going to do anything at all, I put them to far down and I am kicking myself for missing the part about them needing light. I am lucky I have a few more seeds so I will leave these alone and see if any of them do anything, but I will do some more the right way and see if I have the same results everyone else does.
The morning glories had to be planted last night and I was bad and did not take any pictures before I did it. The end result was that the rockwool had 5 very nice seedlings with about 1 1/2 inch roots when I moved them last night. The foamy sponges had 3 very nice seedlings with about the same amount of root on them as the rockwool. The cellulose had 2 nice sized ones, but the roots had all remained inside, so that I could not see them.
I will have to restart the datura experiment and find something else to try instead of the morning glories.
Results so far
5 out of 6 for the rockwool
3 out of 6 for the foamy sponges
2 out of 5 so far for the cellulose sponges.
I thought the way they looked the first couple days that the cellulose was going to do far better than the foam, I am surprised that it came out the way it did.
I have also had a small problem with getting things too warm the last couple days, I made some changes in the lights and put some white sheets of posterboard around the lights to help keep the light on the plants, and a couple of times when I wasn’t paying as much attention as I should have been it has been 80 under the lights.
Pretty amazing for a room that has no heat.
I wish I could keep the rest of the room somewhere near that.
I hope you all are having as much fun with playing with all of the little baby plants as much as I am.
I love being able to see what is going on. Even the failures don’t seem so bad when all I have lost is a few pieces of sponge.

Alice: Daturas take so long to sprout! Mine started germinating and then just stopped. It seems like just when I’m ready to give up and start over with them, they surprise me. Maybe if you pull them up a little in the sponge so they are exposed to the light. It wouldn’t hurt to try. If it doesn’t work, I apologize in advance for wasting your time 🙂

Many of the brugs I planted on 1/28 are beginning to show signs of life! About half that were in sponges were just getting ready to open, so I moved them over to the RW. It just seems a little safer to me.

I had 20 tomato seeds germinate over night in the sponge. They too have been transferred to RW. I just hate to have too much invested in the sponges until we see the long term effect.

A couple of my MG’s have also sprouted 🙂 I have a feeling that I’m going to have something to take pictures of tomorrow. Fingers are crossed. Gretchen

Thanks Gretchen I had decided to try that and then I was not sure if I was seeing any growth on them or not and I was afraid if I touched them, I would really ruin them. I have not given up on them and I intend to see if they can get by my abuse. I told them I would be really good to them if they would just forgive me my one little mistake.
I will have to hope they are more forgiving them my cats, they can hold a grudge for days when I take care of my sister-in-laws dog.
I have started a few small seeds on top of the cellulose and foam sponges and so far nothing from any of those, but some of those seeds were pretty old, so I can’t really blame the method.
Its important in doing the testing to try and remember all of the little details like that so that you don’t blame the method for something that isn’t its fault.
When I did this experiment I nicked nothing, and yet when I did the first MG’s in the sponges I nicked them and all but one germinated very rapidly. So we also have to take that into account.
It is really mind boggling.
I probably need to go get my mad scientist outfit on again, I am starting to think to much.
Hoping for your pictures if not tomorrow by the next day I bet.

here’s my little mg coming to life.

The minute they sprout they take off so fast that its incredible. You will have a good time watching those for the next few days. They are fascinating.

Oh, I can barely keep my hands off them as it is. I guess I didn’t mention here, that my very first ever brug seed sprouted tonight. This is just too much fun 🙂

Gretch I just posted on the other forum after you did, we have got to quit meeting like this. People will talk.

RW has been around for over 30 years. I have a friend that used it 20 some years ago.
As if we don’t have enough. MORE INFO ! ! . LOLOL

LECA is a stone (pebble), will not be applicable for starting seeds 🙁

Datura seeds needs warm weather to germinate properly. i normally plant them in the month of May or June in my area. if u want to have a headstart, u need to use heating mat. othrwise u are depeating ur purpose and seed rot as a result. just my 2 cents worth.

Thanks Mavie
I had them on heat and had to take them off because after I moved lights around they were at 80 degrees and I started to get worried that I would fry them.

I think maybe its time to get a temperature control for my heating pads I had just been trying to get by without the expense.

Alice, do you plant sponge and all after they have germinated and are growing?

I have done it both ways, some things were not at all attached to the sponges and those I took off, the others I have just put in sponge and all.
When I get ready to put everything into bigger pots it will be interesting to see what is going on where the sponges are concerned.
My thinking is still that the roots will eventually just push the sponges or rockwool out of their way.
I won’t have any conclusions for sure until the plants get bigger.

This Automatic Device Is the Tesla of Growing Weed

Many states with medical and adult use marijuana programs allow you to grow your own plants at home — but how many of us actually have a clue about cultivating weed, let alone good weed?

That’s where “homelabs” like Seedo come in. “It does the work for you,” Uri Zeev, CEO of the Tel Aviv-based startup, tells Jane Street. “Seedo is like an auto-grow hydroponic machine. All you have to do is put the seed inside, choose the growing plan, close the door, and let it grow.”

The home device, about the size of a small mini-fridge, is connected to a phone app that allows you to monitor your plant’s progress. A camera installed in the device lets you check in from your phone on how the plant is doing without having to open Seedo’s door. In fact, it’s better not to open it at all, Zeevi says.

For the duration of the three month average grow cycle, the Seedo device regulates the plant’s environment, providing it with just the right amount of light, humidity, heat, carbon dioxide, nutrients, and water, which can be hooked up through the faucet.

Because the device is hydroponic, it doesn’t need soil, hence reducing the chance of pests. The plant goes through four stages after embedding the seed in a rockwool slab or sponge: sprouting, pre-growth, growth, and flowering. At the end of the cycle, you take the plant out of the water at the bottom part, flip it over, hang it upside down, and turn on the machine’s drying phase.

The system has room for one plant every grow cycle, which can yield around three ounces of bud. Depending on the strain, you can milk three or four cycles a year. Each strain has different needs and characteristics, which can make growing weed such a dynamic hobby. The seeds aren’t included with Seedo, but you can find plant clones or seeds at some dispensaries, as well as online. Seeds can also be obtained from plant cones.

And for those looking to branch outside cannabis, Seedo can be used for other plants too, including fruits, vegetables, and flowers. “Basically the machine can grow any type of greens — lettuce, kale, parsley, dill, flowers, tomatoes — but whoever wants to grow cannabis should only buy it where they can,” says Zeevi, though the device is marketed around the world.

Currently Seedo will be available for pre-order in June for the price of $1,600. After that, it will be $2,400. People will be able to obtain them toward the end of the year.

Seedo isn’t the only company to offer an automatic home grow device and connected app. Another Israeli company called Leaf offers a similar product. Both offer the inexperienced access to a hobby that’s otherwise complex and difficult.

“We say that our farmers don’t need to wake up at four o’ clock in the morning,” jokes Zeevi. “They can wake up at ten, check the app, and go back to sleep.”
